I have an older model 36 (pinned barrel) and when I bought it it had virtually no wear on it and looked like it had hardly been fired. The cylinder didn't turn easily and for lack of a better word, it was "stiff" Since, I have put about 1500 rounds through the gun and cleaned it many times. I have also dried fired many times. I believed that by doing all of this I would make the cylinder turn better, it does not. Does anyone have any suggestions or do I need to bring it to a smith? I only live fifty minutes from the S&W factory, should I bring it there?
